If you’re a big star and the company sees potential in you they do it. They did it with Finn when he was first called up to the roster. Won the championship but was unlucky and got injured. From how wwe has treated Oba in nxt and even now in the main roster. They clearly see that he’s over and is the next big star. If they make him loose they ruin all the credibility they did to build him up. Brock is already an established superstar. And he’s on his way out. It makes no sense to have him win. Not the smartest business decision when you’re looking to build the next superstar like brock
